KEY FEATURES AND BENEFITS 

The Cisco 2600 Series supports a wide range of performance and scalability for branch-office networking solutions, allowing businesses to extend a 

cost-effective, transparent network infrastructure to the branch office with the following benefits: 

Investment protection—Support for field-upgradable, modular components on the Cisco 2600 Series allows customers to easily change network 

interfaces without a complete system upgrade of the entire branch-office network. The AIM slot(s) further protects investments by offering the 

expandability to support advanced services such as hardware-assisted data compression, data encryption, ATM data and voice access, or DSP 

digital voice applications. 

Lower cost of ownership—By integrating the functions of switches, channel service units (CSUs), data service units (DSUs), ISDN Network 

Termination 1 (NT1) devices, firewalls, modems, compression or encryption devices, and other equipment found in branch-office wiring closets in 

a single, compact unit, the Cisco 2600 Series provides a space-saving solution that is more manageable. 

Integrated flexible routing and low-density switching—With support of an optional 16-port 10/100 Cisco EtherSwitch ® Network Module, branch 

offices can take advantage of the flexibility of integrated routing and switching functions in one unit for low port densities. This offers high-speed 

connections between individual desktops, servers, and other network resources in a single unit for Layer 2 and allows WAN connection at Layer 3 

through the router. An optional external power chassis provides in-line power to IP phones and to Cisco Aironet ® 802.11 base stations.

Integration of content networking and branch-office routing—With the integration of an optional content-engine network module with branchoffice 

routing, Cisco offers the industry’s first and only router-integrated content-delivery system. Combining intelligent caching, content routing, 

and management with robust branch-office routing, WAN bandwidth is conserved for important branch IP services such as voice over IP (VoIP), 

while simplifying configuration, deployment, and operations. 

Voice and data integration—Cisco offers the industry’s broadest, most scalable multiservice voice and data integration solution set. The Cisco 

2600 Series allows network managers to provide scalable analog and digital telephony without investing in a one-time solution, giving enterprises 

greater control of their converged telephony needs. Using the voice and fax modules, the Cisco 2600 Series may be deployed in both VoIP and 

voice-over-Frame Relay (VoFR) networks. The packet voice trunk network module supports up to 60 simultaneous voice calls as well as 

supporting routing and other services. When used with the ATM AIM, voice over ATM (VoATM) using ATM Adaption Layer 2 (AAL2) or 

AAL5 can be deployed. 

Enterprise and provider-class solution—This solution meets the requirements of multiservice enterprises and their managed service customerpremises-equipment 

(CPE) providers with high-reliability features, multiple WAN connections, and the ability to migrate from data-only to timedivision 

multiplexing (TDM) voice and from data to packetized voice and data infrastructure. 

Security—With the integration of optional VPN modules, Cisco IOS Software-based firewalls and Intrusion Prevention System (IPS), contentengine 

network modules, or intrusion detection network modules, Cisco offers the industry’s most robust and adaptable security solution for 

branch-office routers. VPN modules can be used to provide up to 10 times the performance over software-only encryption. Additionally, the new 

Cisco Intrusion Detection System Network Module allows decryption, tunnel termination, and traffic inspection at the first point of entry into the 

network while freeing the router CPU from process-intensive IDS tasks. 

Business-class DSL connectivity—With the WIC-ADSL, WIC-1ADSL-I-DG, WIC-1ADSL-DG, WIC-1SHDSL, and WIC-1SHDSL-V2 modules 

added to the Cisco 2600 Series offers a broad range of business-class broadband options with scalable performance, flexibility, and security for 

branch and regional offices. The Cisco 2600 Series provides an ideal solution for a variety of businesses requiring high-speed business-class DSL 

connectivity on a secure, high-performance modular platform. 

Increased memory capacity on Cisco 2600XMs—The memory capacity of the Cisco 2600XM platforms can now be increased to 256 MB 

of synchronous dynamic RAM (SDRAM) using a new 128-MB SDRAM dual in-line memory module (DIMM). This new 128-MB DIMM offers 

higher-density memory, providing the ability to support memory increases to 256 MB of DRAM (with the correct ROMmon). 

The Cisco 2600 Series brings a cost-effective combination of versatility, integration, and increased performance to remote branch offices with the

model, one network module slot, two or three WIC slots, and one or two AIM slots as well as one 115.2-kbps console port and one 115.2-kbps 

auxiliary asynchronous port are offered. 

Network Module Options 

Network modules help enable the Cisco 2600 Series to be customized to meet the needs of virtually any branch office. These modules support a 

broad range of applications, including multiservice voice and data integration, analog and ISDN dial access, ATM access, integration of low-density 

switching, IDSs, content networking, and serial device concentration (refer to Table 5 for the complete list of supported network modules for the 

Cisco 2600 Series). Other advantages of the network module are to provide integrated services onto one platform for greater management of services 

and ease of operations. By offering network modules such as the Cisco EtherSwitch Network Module, content engine, network analysis, and 

intrusion detection network modules, more services are integrated onto a single platform. These modules provide the advantage of integrating 

switching, content networking, or intrusion detection with routing onto one platform for greater management and ease of operation. 

The Cisco 16-Port 10/100 EtherSwitch Network Module combines robust Layer 3 flexible WAN routing with low-density line-rate Layer 2 

switching, providing straightforward configuration, easy deployment, and integrated management in a single platform (see Figure 2). The Cisco 

EtherSwitch modules use the powerful features available in both Cisco IOS Software and Cisco Catalyst switching, with hardware supporting 802.1p 

Layer 2 prioritization, while Cisco IOS Software supports Layer 3 Differentiated Services (DiffServ) and class-of-service (CoS) markings for critical 

business data.

Figure 2. Cisco 16-Port EtherSwitch Network Module 

Cisco content-engine network modules offer the industry’s first and only router-integrated content-delivery system (see Figure 3). Combining 

intelligent caching, content routing, and management with robust branch-office routing conserves WAN bandwidth for important branch IP services 

such as VoIP, while simplifying configuration, deployment, and operation. 

Figure 3. Cisco Content Engine Network Modules 

The Cisco IDS Network Module is part of the Cisco integrated IDS network security solutions that help enable organizations to protect assets and 

reduce operating costs (see Figure 4). 

The Cisco IDS Network Module is an integrated network module that delivers full-featured intrusion protection. The network module runs the latest 

Cisco IDS Sensor Software and is at feature and function parity with the Cisco IDS Sensor portfolio. For the first time you can now locate IDS as an 

integral part of the branch-office router, and monitor traffic from all interfaces on that router. If VPN generic routing encapsulation (GRE) and IP 

Security (IPSec) tunnels are terminating at the router, the module can monitor the decrypted traffic through collaboration with IPSec VPN and GRE 

traffic-an industry first in VPN deployments. The network module can be deployed at branch offices and used to protect branch-office networks, 

thereby isolating threats from the corporate site. 



Page 8 of 26

Figure 4. Cisco IDS Network Module (part number NM-CIDS-K9) 

The Cisco Network Analysis Module (NAM) addresses the need for multiservice network management and traffic monitoring in enterprise branch 

offices. The Cisco 2600, Cisco 3660, and Cisco 3700 series NAM is an integrated traffic-monitoring network module that helps enable network 

managers to gain application level visibility into network traffic with the ultimate goal of improving performance, reducing failures, and maximizing 

return on network investments. The Cisco 2600, Cisco 3660, and Cisco 3700 series NAM expands the Cisco NAM solution currently available for 

Cisco Catalyst 6500 Series switches and Cisco 7600 Series routers. Cisco NAMs give network managers visibility into all layers of network traffic by 

providing application level Remote Monitoring (RMON) functions based on RMON2 and other advanced MIBs. They provide intelligence to 

analyze traffic flows for applications, hosts, conversations, and network-based services such as QoS and VoIP. Cisco NAMs come with an 

embedded, Web-based traffic analyzer, which provides full-scale RMON and troubleshooting capabilities that are accessible through a Web browser. 

Multiflex Voice/WAN Interface Card and WIC Options 

The Cisco 2600 Series WIC slots now support 20 interface cards with the introduction of the 1-port xDSL and 1- or 2-port analog modem WICs. The 

Cisco 2600 Series of modular routers support both asymmetric DSL (ADSL) and the G.shdsl WICs. These offerings bring high-speed business-class 

broadband service to the award-winning Cisco 2600 Series of multiservice routers. Now small and medium-sized businesses (SMBs), enterprise 

branch offices, and service provider-managed service users can take advantage of a highly flexible and scalable solution for data-only or voice and 

data integration, with secure VPN options. 

The single- and dual-port multiflex voice/WAN interface cards (VWICs) combine WIC and VIC functions to provide unparalleled flexibility, 

versatility, and investment protection. Supporting up to T1 and E1 rates with integrated T1 CSUs and DSUs or E1 DSUs, the multiflex VWICs can 

be used in data-only, channelized (drop and insert) voice and data integration applications, as well as packet voice and data connections to a PBX or 

the Public Switched Telephone Network (PSTN). (Packet voice requires the use of the high-density voice trunk network module.) Unlike traditional 

multibox voice and data components, when used in a Cisco 2600 or Cisco 3700, the T1/E1 multiflex VWICs deliver a single-box voice and data 

platform that provides a graceful migration from data only to channelized voice and data, to packet voice and data. (Refer to Table 6 for the complete 

list of supported VWIC modules for the Cisco 2600 Series.) 



Page 9 of 26

Figure 5. Dual-Port Multiflex T1 VWIC with Drop and Insert 

The dual-port serial WICs feature the new Cisco compact, high-density smart serial connector to support a wide variety of electrical interfaces when 

used with the appropriate transition cables. Ports on each card can be configured individually to support a variety of synchronous or asynchronous 

protocols. 

AIM Options 

All Cisco 2600 Series routers are equipped with an internal slot to support one or two field-installable AIMs. AIMs use function-specific hardware to 

offload the main router CPU and accelerate processor- or resource-intensive services, yielding dramatically higher throughput and higher 

performance than a software-only implementation. The AIM slot has access to virtually all of the router resources, including the main system bus. 

The TDM bus and the serial communications controllers make this a very flexible and powerful feature. Because the AIM is internally mounted, 

external slots remain available for integration of other modular components such as CSUs and DSUs, WAN interfaces, or other devices such as 

modems or packetized voice and fax processors. 

For example, the data encryption AIM offloads encryption processing from the Cisco 2600 Series CPU, providing 10 times the performance over 

software-only encryption. The AIM-VPN/BPII, new AIM-VPN/BPII_PLUS-PLUS, AIM-VPN/EPII, and new AIM-VPN/EPII-PLUS support a 

maximum number of 800 remote access tunnels when using the Cisco 2600 models. These modules offer hardware-accelerated Digital Encryption 

Standard (DES) and Triple DES (3DES) and the new AES encryption at speeds up to 80-Mbps performance (maximum based on 1400-byte packet 

size). In addition, these modules support hardware-assisted Layer 3 compression services, allowing bandwidth conservation for lower network 

connection costs, with the new AIM-VPN/BPII_PLUS-PLUS and AIM-VPN/EPII-PLUS providing cryptographic-optimized wide key AES support 

(192 and 256). 



Page 10 of 26

Figure 6. EPII-PLUS Encryption AIM 

The AIM ATM provides a high-performance hardware-based ATM access solution for one to four T1 or E1 connections supported by the T1 or E1 

VWICs (for example, VWIC-1MFT-T1). This frees the network module slot to support other functions. When used in combination with a highdensity 

voice network module (part number NM-HDV-xxx), the ATM AIM supports AAL2 and AAL5 VoATM. In addition, the AIM-VOICE-30 

and AIM-ATM-VOICE-30 AIMs provides a cost-effective solution for supporting voice services or digital voice over ATM (AAL2 and AAL5) 

support, without the use of a network module. (Refer to Table 7 for the complete list of supported AIM modules for the Cisco 2600 Series.)
